For 15 years, from 1910 to 1924, Erich Mühsam, the most famous German anarchist, documented his life: in detail, stylistically pointed, unflinchingly honest even towards himself, and never boring. What makes these diaries so captivating is the keen perspective of a world-changer. Mühsam wanted to practically experiment with anarchy. For him, anarchy meant living without moral blinders, without regard for conventions, and he proved that it is possible. Writing is also action; in every sentence, there is an expectation of the upheaval he actually brings about: the Munich Soviet Revolution is also his, and the revenge of the Bavarian judiciary hits him hard. Mühsam's diary is a monumental work that is yet to be discovered. It will be published in 15 volumes and simultaneously as an online edition. The meticulously edited text volumes will be accompanied by annotations online.
